Introduction/Objective. Hypodontia is a common dental anomaly that occurs either in a non-syndromic form or as a part of various syndromes. It is considered a multifactorial condition with genetic, epigenetic and environmental influences, the interplay of which can lead to various anomalies in tooth size and number. The aim of this study was to assess mesiodistal tooth dimensions in Serbian hypodontia orthodontic patients and compare them to healthy controls using digital study models. Methods. Fifty subjects (30 females, 20 males) divided into two groups - 25 with hypodontia (15 females, 10 males) and 25 gender-matched controls (15 females, 10 males) were included in the study. Alginate impressions were taken and plaster models poured, digitized and imported into the software where mesiodistal dimensions were obtained. Results. Intra-operator reliability was high. All teeth in the hypodontia group had smaller mesiodistal dimensions compared to controls. Statistical significance was noted for all teeth except for upper canines. No statistically significant differences were found between males and females in neither the hypodontia nor the control group, except for lower canines, which were significantly smaller in both hypodontia and control females. The most commonly missing teeth were upper lateral incisors, and lower and upper premolars. Conclusion. Hypodontia group presented with smaller mesiodistal dimensions compared to controls. The greatest difference in mesiodistal dimensions was found in upper lateral incisors and lower first molars. Lower canines were significantly larger in males compared to females in both groups.

The study models of a group of adult Sri Lankan patients with clefts of the secondary palate were investigated. Tooth-size and arch-dimension comparisons were made with a comparable control group. Significant differences were found between the cleft and control groups in tooth sizes, chord lengths, and arch widths. The cleft group dimensions were generally smaller than those of the control group. Overjets were larger in the cleft group.

ABSTRACT Objective: To investigate whether there is an association between suicidal ideation (SI) and allergic diseases in adults. Methods: This was a comparative cross-sectional study involving individuals ranging from 20 to 50 years of age recruited from a university hospital in the city of Guadalajara, Mexico. We included patients with a confirmed diagnosis of allergic asthma, those with a confirmed diagnosis of allergic rhinitis, and healthy controls. All subjects completed the Beck Depression Inventory-II (BDI-II), which includes an item that evaluates the presence of suicidal thoughts or desires within the last two weeks, in order to identify SI. Results: The sample comprised 115 patients with allergic asthma, 111 patients with allergic rhinitis, and 96 healthy controls. The number of individuals identified with SI in the three groups were, respectively, 17 (14.8%), 13 (11.7%), and 8 (8.3%). Regarding the presence of SI, no statistically significant association was found in the allergic asthma group (OR = 1.98; 95% CI: 0.78-4.64; p = 0.154) or in the allergic rhinitis group (OR = 1.46; 95% CI: 0.58-3.68; p = 0.424) when they were compared with the control group. However, the presence of depression was associated with SI in the three groups: allergic asthma (OR = 12.36; 95% CI: 2.67-57.15; p = 0.001); allergic rhinitis (OR = 6.20; 95% CI: 1.66-23.14; p = 0.006); and control (OR = 21.0; 95% CI: 3.75-117.36; p < 0,001). Conclusions: In comparison with the control group, no association was found between SI and the groups with allergic diseases. In contrast, there was association between SI and depression in the three groups.

Onychophagia and onychotillomania are rarely seen in clinical practice and are considered undervalued. The study aims were to determine the prevalence of onychophagia and onychotillomania habit in the patient group with hand nail damage and control group, to determine which would be the target population to educate. Patients were interviewed about self-destructive habits. Excel and SPSS were used for data analysis. In the nail damage group, 28.6% of the respondents showed self-destructive habits and past habits – 31.4%. In the control group, the result was 22.9% and 31.4%. For 74.3% of patients the cause of nail damage was skin disease (including 61.54% of respondents with nail damage who have psoriasis), for 5.7% it was age-related nail changes, for 20% traumatic damage and for 57.14% of them it was a result of self-destructive habit. In the nail damage group both – present and past self-destructive habits are higher than in the control group, but it has no statistical significance (p=0.785). 1)The prevalence of onychophagia and onychotillomania does not differ between patients and control group. 2)General education of the population is necessary to actualize this problem, which can worsen nail changes.

Background Antioxidants show nephroprotective effect against vancomycin associated nephrotoxicity (VAN) in animals. This study aimed to assess the ascorbic acid nephro-protective role against VAN clinically. Methods Forty-one critically ill patients were randomly assigned to one of two groups: intervention group (vancomycin IV plus ascorbic acid, n=21) or control group (vancomycin IV only, n=20). Primary outcomes were the incidence of VAN and the absolute change in creatinine parameters, while mortality rate was the secondary outcome. Nephrotoxicity was defined as an increase in serum creatinine (S.cr) by at least 0.5 mg/dL or 50% of baseline for at least two successive measurements. This study is registered at Clinicaltrials.gov (NCT03921099), April 2019. Results Mean absolute S.cr increase was significant when compared between both groups, P-value = 0.036, where S.cr increased by 0.05(0.12) and 0.34(0.55) mg/dL in the intervention and control groups, respectively. Mean absolute Cr.cl decline was significant when compared between both groups, P-value = 0.04, where Cr.cl was decreased by 5.9(17.8) and 22.3(30.4) ml/min in the intervention and control groups, respectively. Incidence of VAN was 1/21(4.7%) versus 5/20(25%) in the intervention and control groups, respectively (RR: 0.19; CI: 0.024–1.49; P-value = 0.093). Mortality was higher in the control group; however, it was not statistically significant, P-value = 0.141. Conclusion Co-administration of ascorbic acid with vancomycin preserved renal function and reduced the absolute risk of VAN by 20.3%, however, the reduction in VAN incidence didn’t reach statistical significance level. Further large multicenter prospective trials are recommended.

This research attempted to explore the effects of divergent and convergent tasks on the successful reading of EFL students at the preparatory stage. To verify the analysis, the null hypothesis was established that states "There are no differences of statistical significance at the level of (0,05) among the mean of scores of the experimental group who study according to divergent and convergent task technique and the mean of the scores of the control group who study according to the regular method".  The experimental approach is used by designing two equivalent experimental groups of 32 students studying the technique proposed, and an 8-week (2019-2020) control group of 32 students, three classes each week using the Google Classroom Platform and Telegram. The present study utilized the platform Google Classroom (GC) and Telegram as an educational platform to assist students during their course learning process. The writing skills test was administered after checking with the experts. The results show that there are statistical differences at level (0,05) between the average of the experimental and control groups' reading skills and those of the experimental group. This difference is because the experimental group uses divergent and convergent tasks.

ABSTRACT Objectives:  To assess the null hypothesis that there is no difference in the rate of dental development and the occurrence of selected developmental anomalies related to shape, number, structure, and position of teeth between subjects with impacted mandibular canines and those with normally erupted canines. Materials and Methods:  Pretreatment records of 42 subjects diagnosed with mandibular canines impaction (impaction group: IG) were compared with those of 84 subjects serving as a control reference sample (control group: CG). Independent t-tests were used to compare mean dental ages between the groups. Intergroup differences in distribution of subjects based on the rate of dental development and occurrence of selected dental anomalies were assessed using χ2 tests. Odds of late, normal, and early developers and various categories of developmental anomalies between the IG and the CG were evaluated in terms of odds ratios. Results:  Mean dental age for the IG was lower than that for the CG in general. Specifically, this was true for girls (P &lt; .05). Differences in the distribution of the subjects based on the rate of dental development and occurrence of positional anomalies also reached statistical significance (P &lt; .05). The IG showed a higher frequency of late developers and positional anomalies compared with controls (odds ratios 3.00 and 2.82, respectively; P &lt; .05). Conclusions:  The null hypothesis was rejected. We identified close association of female subjects in the IG with retarded dental development compared with the female orthodontic patients. Increased frequency of positional developmental anomalies was also remarkable in the IG.

Abstract Background Epilepsy is a serious common neurological disorder that can affect any age. Cognitive functions are highly prevalent in patients with epilepsy and is more likely to occur in patients with idiopathic generalized epilepsy (IGE). Associations were found between cognitive functions and brain volume loss in patients with epilepsy. Objective This work was carried out to assess the volumetric changes in brain of epileptic patients to use it as a biomarker for cognitive dysfunction in adult and adolescent patients with epilepsy. Patients and Methods A case control study was conducted to include 61 patients, 20 of which diagnosed with idiopathic generalized epilepsy (IGE), 21 with temporal lobe epilepsy (TLE) and 20 with frontal lobe epilepsy (FLE) who were selected from the epilepsy outpatient clinic in Ain Shams university hospitals along with 23 age and sex matched healthy controls. Both cases and control groups were subjected to Magnetic resonance imaging MRI brain volumetry and detailed cognitive testing. An informed consent was taken from each adult patient, guardian of adolescent patient and healthy control. Results Statistically significant difference in comprehension subcategory of the Wechsler adult intelligence scale (WAIS) between patients with IGE and healthy controls denoting poorer social judgment in the IGE group. The IGE group also showed poorer performance in digit symbol subcategory of the same test denoting worse psychomotor speed and sustained attention. Also, significant difference in similarities subcategory was found between TLE group and control group denoting poorer abstract thinking among the TLE group. The IGE and TLE groups also showed lower attention and concentration than control group in the mental control subcategory of the Wechsler memory scale (WMS) yet failed to show superiority over each other. No statistically significant difference was found on comparing the whole brain volume between cases and control groups. A statistically significant direct relationship was found between the arithmetic subcategory of WAIS and the whole brain volume of the patients among the patients of the FLE group. Conclusion Patients with IGE had worse psychomotor speed, sustained attention and concentration than healthy controls in addition to poorer social judgment. Also, patients with TLE showed lower attention and concentration together with poorer abstract thinking despite normal IQ. The study also concluded that increased whole brain volume in patients with frontal lobe epilepsy is associated with better mathematical problem solving.

The aim of this study was to investigate the influence of 24-h sleep deprivation on the muscle strength of young, healthy and physically fit people. The research material consisted of physical education students. In total, 67 people participated in the study, including 38 women and 29 men. Respondents were divided into an experimental group “E” of 44 persons subjected to 24-h sleep deprivation and a control group “C” of 23 persons. Students completed the Epworth Sleepiness Scale (ESS) measuring daytime sleepiness. Students performed measurements of the maximum strength of knee joint extensor and flexor muscles. Measurements of muscle strength of flexors and extensors of the knee were taken on a UPR-02 A/S chair with Moment II by Sumer software. ANOVA (analysis of variance) was used to determine the significance of differences between experimental “E” and control “C” group. Statistical significance was defined at the level of p ≤ 0.05. Statistically significant differences were observed in the change of strength levels between groups at the strength moments of right (p < 0.05, η2p = 0.16) and left (p < 0.05, η2p = 0.08) knee muscles extensor. Changes in extensor muscle strength are significant for students with left dominant legs.

Background: Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm. The pathogenesis of CML is based on the oncoprotein termed BCR‐ABL1. TET2 initiates DNA demethylation and is frequently mutated in hematological malignancies including CML.(1) The relation between TET2 acquisition and CML transformation and/or imitinab resistance is needed to be investigated. (2) Aim: To evaluate Ten Eleven Translocation 2 gene (TET2) single nucleotide polymorphism (SNP) (rs2454206, rs34402524, rs61744960) in chronic myeloid leukemia (CML) in relation to the disease prognostic criteria. Materials & Method: The study included 84 subjects; 54 CML in chronic phase and 30 healthy subjects as control group matched for age and sex. Routine investigations including CBC, bone marrow aspiration, biochemical investigations and molecular study were performed in CML patients to identify the disease stage. DNA extraction and SNP assay for TET2 gene polymorphism was done using (Thermo-Fisher predesigned SNP, USA) PCR prism 7500. Results: The mean age was 45.98±15.7 yrs in CML patients and   39.3±6.587 yrs in control group (p>0.05). TET2 SNP rs 34402524 was either heterozygous and homozygous in CML (48%,and 46.2%) but was mainly homozygous among control (80%) group (p=0.012). TET2 SNP rs 2454206 cases within CML (65.4%) and control (63.3%) group had wild patterns (p=0.046). TET2 SNP rs 61744960 showed a homozygous pattern among all groups (CML and control) showing no statistical significance (p=0.528). TET2 SNP in CML cases did not alter the prognostic criteria as no statistical significance was noted (p>0.05) yet, it was significantly related to spleen size in rs 34402524 where homozygous group had huger sizes and higher BCR-ABL1 levels 6 months after starting TKIs (p<0.05). Conclusions/Recommendation: TET2 SNP is a common in Egyptian chronic myeloid leukemia. TET2 SNP rs 3442524 was associated with huger spleen size and higher BCR-ABL1 levels after 6 months of starting TKIs suggesting disease progression.

AbstractThe purpose of the study was to compare serum visfatin levels between patients with acromegaly and healthy controls and to evaluate the relationships between visfatin levels and epicardial fat thickness (EFT), carotid intima media thickness (cIMT), and ankle brachial index (ABI). We conducted a cross-sectional case-control study of 54 patients with acromegaly (37 females and 17 males) and 34 healthy controls (22 females and 12 males). Serum visfatin was measured by ELISA. Acromegalic and control participants and those with active or controlled acromegaly were compared with respect to their serum visfatin, clinical and metabolic parameters, EFT, cIMT, and ABI. Linear correlation was used to identify associations between these parameters and visfatin in all participants. Serum visfatin and glycated hemoglobin (HbA1c) were higher in the acromegaly group than in the control group (p<0.001 and p=0.007, respectively). There was no difference in visfatin between the active and controlled acromegaly groups, but HbA1c was higher in the active than the controlled acromegaly group (p<0.04). EFT, cIMT, and ABI were similar between the acromegaly and control groups and between the active and controlled acromegaly groups. Serum visfatin positively correlated with HbA1c, growth hormone (GH), and insulin-like growth factor-1 (IGF-1)/upper limit of normal ratio (r=0.245, p=0.024; r=0.259, p=0.017; and r=0.282, p=0.009, respectively). This study has revealed that a high visfatin level is associated with glycemic dysregulation and higher levels of GH and IGF-1 in acromegalic patients.
